This invention relates to pumps, and more particularly to a pump operating mechanism. y

One of the objects 'of the present invention is to provide novel means for mounting and drivably connecting a pumpto a power plant, such as an internal combustion engine.

Another object of the invention is to provide a pump inwhich actuation thereof does not detract from the useful output of the power plant. A

Another object of the invention is to provide an engine driven pump in which rotary shafts are eliminated.

Another object of the invention is to provide a pump for an automotive vehicle in which the actuation of the pump is produced by movement of the power plant relative to its supporting frame.

Another object of the invention is to provide a pump for an automotive vehicle hav# ing arpower plant bodily movable to a limited extent in its supporting frame, in which actuation of the pump is produced by the relative movement of the power plant.

Other objects of the invention will appear from thefollowing description, in connection with which a preferred embodiment has been illustrated in the accompanying draw- V ing, in which Fig. 1 is aside elevation of a power plant adapted to be bodily movable in a supporting4 frame Fig. 2 is an end elevation of the power plant shown in Fig. 1 and illustrating the,

operative connection of the improved pump.

It is Well known that reciprocating engines are subject to vibrations, some of which are produced by secondary unbalanced forces and others by torque variations due to a small number of cylinders. The variations in torque impulses are noticeable in all en- `gines having reciprocating parts.

A convenient means of preventing the vibrations from being transmitted to the env gine supporting frame, or to a vehicle, for example, is illustrated in Fig. 1, in which the engine 10 is mounted at only two points, one of which is at the rear or driving end of the engine whereat the extension 11 issupported in a yielding mounting 12 adapted to be' secured to the engine frame 13 by any desired means, such as arm 14. The front end of the engine is supported by a member 16,

preferably located in an axis which includes the engines center of gravity 17 and the center of extension l1. Member 16 is also preferably supported in a yielding mounting 18, which is connected to the frame 13 by a bracket 19. i

The above described method of mounting the engine upon two spaced parallel supports allows the power plant to oscillate as a whole about the axis A-A, and the motion is prevented from being transmitted to the frame 13 by the members 12 and 18. 1f desired, excessive movement may be damped by the use of a leaf spring 21 secured at one of its ends to the engine case 10 and slidably guided by the frame 13 at its other end.

1 Observation of an engine operating in thel above described support shows that it is possible, under some conditions, to obtain a total oscillatory movement of substantially four inches at the upper front end of the engine, designated by 22, and that the amplitude progressively decreases to substantially zero at support 12.

In accordance with the present invention, the oscillatory movement of an engine mounted in the manner described above is employed to operate suitable` pumping mechanism, thereby converting energy otherwise lost into useful work. To this end, a puin cylinder 15 (Fig. 2) is preferably connecte by a ball and socket joint 23 to a .bracket 24 secured to the engine frame 13. Within the cylinder is a piston 26 pivotally connected to the power plant. atany point subject to oscillation such as the top of the engine, by rod 25 preferably having a ball and socket connection 27 with a bracket 28 secured to the engine by screws 29.. The total oscillatory movement ofthe engine is indicated by lines moves piston 26 upwardly and draws a l charge of air through pipe30 and past check valve 31 into the cylinder 15.. The return by pipe 34 to an desired movementmoves the piston 26 downwardly to compress the air therein and force it past outlet checkvalve 32 throu h conduit 35 to the reservoir 33, from whic it may be led, part, such as a hydraulic vehicle rake. A blow-olf valve 36 may be used,- if desired, for maintaining the pressure within the reservoir 33 at an desired pressure. The above describedY pump is also adaptable to the pumpin of other fluids and may be used for'provi ing a supply ofl fuel or 'other liquid by connecting inlet pipe 30 to any suitable source of supply.

Other uses will be apparent to those skilled inthe art, and although a'preferred embodiment of the invention has been shown and described, it is understood that this showing and description are illustrative only and that the invention is not regarded as limited to the form shown and described, or otherwise,A
